Software-generated error messagesThese messages appear if a problem or conflict is detected by the applicationprogram, the operating system, or both. Error messages for operating system andother software problems are generally text messages, but they also can be numericcodes. For information about these software error messages, see the informationsupplied with the operating system and application program.Device Suggested actionSoftware problem To determine if problems are caused by the software, verify that:1. Your computer has the minimum memory requirements needed to use thesoftware. For memory requirements, refer to the information that comes withthe software.Note: If you have just installed an adapter or memory, you might have amemory address conflict.2. The software is designed to operate on your system.3. Other software works on your system.4. The software that you are using works on another system.If you received any error messages when using the software program, refer tothe information that comes with the software for a description of the messagesand solutions to the problem.If the items above are correct and the problem remains, contact your place ofpurchase.Suspected software problem.Troubleshooting the Ethernet controllerThis section provides troubleshooting information for problems that might occurwith the 10/100 Mbps Ethernet controller.Network connection problemsIf the Ethernet controller cannot connect to the network, check the following:v Make sure that the cable is installed correctly.The network cable must be securely attached at all connections. If the cable isattached but the problem persists, try a different cable.If you set the Ethernet controller to operate at 100 Mbps, you must use Category5 cabling.If you directly connect two workstations (without a hub), or if you are not usinga hub with X ports, use a crossover cable.Note: To determine whether a hub has an X port, check the port label. If thelabel contains an X, the hub has an X port.v Determine if the hub supports auto-negotiation. If not, try configuring theintegrated Ethernet controller manually to match the speed and duplex mode ofthe hub.v Check the LAN activity light on the rear of the computer. The LAN activity lightilluminates when the Ethernet controller sends or receives data over the Ethernetnetwork. If the LAN activity light is off, make sure that the hub and network areoperating and that the correct device drivers are loaded.v Make sure that you are using the correct device drivers, supplied with yoursystem.v Check for operating system-specific causes for the problem.v Make sure that the device drivers on the client and system are using the sameprotocol.Chapter 6.
